MPLAB X, curiosity 8-bit HPC, PIC18F27J13 .. no joy

My client selected the 18F27J13 because XLP, RTCC, SPI, I2C.  So I ordered the DM164136 and the 28pin PDIP of 27J13.  The Curiousity came with 16F18875.  I practiced with that before trying the 18F27J13.  It seems that the J13 family is not supported by MPLAB with my hardware configuration.  I would like to understand why the curiosity status turns red when the J13 family is selected.  Is it a hardware problem or maybe an issue with a properties file somewhere?
 
Before ordering, I reached out to tech support asking if the chosen hardware components are compatible.  A week later, someone replied and stated (without evidence) that the HPC and 18F27J13  were compatible.  This is terrible support.

    I suggest you report this to support.

    I opened a ticket last week. I added more detail since then.. Still waiting for an answer.  So I try my luck in the forum.

    Maybe they provided a phone number and call in id you could use to talk directly to someone.

    I think there's two issues.
     
    First, the PKOB onboard debugger/programmer doesn't support the J13 (or at least it didn't last I checked). PKOB only supports one or two devices in the entire 18FJ series.
     
    Second, the hardware would need a little modification to support the VDDCORE/VCAP connection on pin 6. Usually pin 6 of the 28-pin package is RA4, which is connected to LED D2/R4 on the Curiosity. You could remove those and add a VCAP, but you're still stuck with issue #1

    Well, I finally got a response from TechSupport.   It seems to me that the 8-bit Curiousity HPC is only for experts since the typical noobie will just assume that the HPC is for whatever PIC they decide to use.  That is what it's web page implies.  I am not pleased that support verified these components were compatible when in fact they were not.   A waste of time and money for me.

    Dear Robert,

    I have verified on MPLAB X IDE v5.10.
    It seems PIC18F27J13 is not supported by Curiosity when I create a project for it.

    The HPC board indeed has a slot for 28-pin PDIP devices.
    Currently, the Curiosity PKOB on-board do not support PIC18F27J13.
    One thing the user could do to program PIC18F27J13 sitting on DM164136 (https://www.microchip.com...oductDetails/dm164136) is to have jumper wires from the pin headers to PICkit 3 connector.

    Please review 28-Pin SPDIP Pin Diagram on page 5 of the datasheet (http://ww1.microchip.com/...iceDoc/30009974C.pdf).

    PICkit 3 product page - https://www.microchip.com...roductDetails/PG164130

    PICkit 3 poster as guide - http://ww1.microchip.com/...eviceDoc/50002010B.pdf

    If the user is concerned the PKOB might interfere with the PICkit 3 programming, I would suggest unplugging the USB port from the HPC board, and powering the device from the PICkit 3 or by using an external power.

    Another alternative is using AC162049-2 instead of the HPC board.

    AC162049-2 product page: https://www.digikey.com/c...9-and-ac162049-2/20241

    Another AC162049-2 product page: https://www.microchipdire.../search/all/ac162409-2

    ICD 3 (alternative to PICkit 3) product page: https://www.microchip.com...roductDetails/DV164035

    Warm wishes,
    JJ

    My client selected the 18F27J13 because XLP, RTCC, SPI, I2C.
    ...
    Before ordering, I reached out to tech support asking if the chosen hardware components are compatible.  A week later, someone replied and stated (without evidence) that the HPC and 18F27J13  were compatible.

    [Edit]
    In fact, I now realize that the 'K13 and other 'K' devices are programmed without applying high voltage to the MCLR pin.  The problem remains with VCAP as Jerry Massina pointed out.  That would require a user to kludge in a capacitor if it ever happened that Microchip decides to support it.
     
    I would still recommend a 'K42, and not just because of immediate Curiosity support.
    [/Edit]
    That's just pathetic.  The Curiosity PKOB (PICkit On Board) programmer only works in LVP (Low Voltage Programming) mode.  The 'J13 does not have LVP mode.  Period.  (Neither do the 'J50 and 'J53 devices, which I have used in projects---I prototyped with solderless breadboards and hand-wired hole-per-pad perf boards with ground planes on both sides).
     
    There are certain other devices that are not presently supported by the Curiosity boards, but there is no "real" reason they couldn't be made to work (with software changes from Microchip).
     
    Bottom line:  There are a number of devices that were not originally supported in Curiosity boards, but have been enabled by recent MPLABX releases.  However---don't expect software upgrades on the Curiosity PKOB to support 18FxxJxx devices.  Period.
     
    Suggest to client that a member of the 'K42 family would be much more appropriate, and I know for a fact that the PIC18F27K42 works on the Curiosity HPC.  No guess work here.  I have used them together.
     
    Also the PIC18F27K42 has a number of advanced features that make it superior for many applications.  Older families like the 'Jxx devices will continue to be available, but the newer families are, generally speaking, cheaper, with possibly lower power or higher speeds (or, even, both), etc...
     
    Regards,

    Dave

    I recently found the Docs/DeviceSupport matrix in MPLAB X.  It matches PICS to program/debug hardware but does not include Curiousity boards in the matrix.
     
    K42 has a yellow PKOB status in MPLAB.  I assume this is caused by the Masm=yello for not finished testing. The K40 is fine for PK3,PK4 or Curiosity HPC. And it is on an DM182027 Evaluation board

    27J13 needs PK3,ICD3

    Hi,
    I have used PIC1F8F46K42 and PIC18F47K42 with HPC curiosity.
    They both work fine so I think there is no issue with the 28 pin versions PIC18F2xK42 devices.
    Yellow means it is not yet production "support". It needs at least 6 to 12 months to become green (production support) but from my experience during many years yellow is as good as green. 
    It is just a matter of time until yellow support becomes green support.
    Regards
